.To all whom it may concern:

le 1t known that l, Hnnnnn'r lV. lVoLrr, residing at St. Louis, Missouri, and being certain new and useful Improvements in Carlmcs, of which the following 1s a full, clear, and exact description, suchA as will l l a-citizen of the United States, have invented l l I i l l enable others skilled in the art to which it Y appertains to make and to use 'the san1e,'| reference being had to the accompanying! drawings, which illustrate the preferre l form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described. asit is obvious that various l modifications thereof will occur to persons l skilled in the art.

1n' said drawings: Figure 1 is a plan View i of one form of my improved carlme. Fig. l 2 is an elevational view thereof. Fig. 3 is a central vertical sectional view. Fig. 4 is a central vertical sectional view of a'slightly modified form wherein a Z-shaped pressing issubstituted for the channel shaped pressing shown in Fig. 3. Fig. 5 is a"plan view of amodified form. Fig. (3 is an elevational view of the modification shown in Fig. 5. Fig. 7 is a central vertical sectional view of the modification shown in Figs. 5 and 6. Fig. 8 is a plan' view of a trussed form of carline. Fig. 9 is an elevational view of thedevice shown in Fig. 8. Fig. 10 lis a central vertical sectional view of the modifian elevational View of a further modification. Fig. 12 is a central vertical sectional view of the device shown in' Fig. 11. Fig. 13 is a modification showing an adjustable tension member connected with tbe com pression member of the carline. Fig. V14: is a central vertical sectional view of the The object of the invention is to provide a new and improved form of carline composed of a cambered compression member and a tension member connected thereto relatively at the middle portion thereof within the camber of thecompression member, and includes modifications. and details `of construction all as hereinafter more fully described and specifically pointed out in the claims.

. Referring to the parts and specifically to the modifications shown in Figs. 1 to 9 inclusive, 1 is the compression member of my 'improved carline, which is shown as cornposed of a rolled channel with vertically disposed fianges 2 and horizontal web portion The anges 2 are shorter than the web portion,.said flanges terminating at the side plates et, either within thc area of the said plates or extending to approximately the outer faces thereof` the web 3 preferably extending downwardly against the outer faces of said side plates as shown at 5 in said Figs. 1 to 9 inclusive, which said extensions 5 are secured to the side plates 4: by bolts (3 extending horizontally through the web extensions and said side plates.

ln the modifications shown in Figs. 11-14 inclusive the compression member terminates at the inner side of the side plates 4 and flangedf gusset platesiare connected with the flanges Q of the compression members and are secured by bolts G to the side plates.

In Figs. 1 to T inclusive the carline is a lcomposite structure comprising the channel 1 and connected pressed members 9, 10 or 11,

member, with its lower or tension flange 12 free.

The modification shown in Fig. 4F includes a Z-shapcd pressed member 10 with bottom flange 12 and an oppositely disposed flange 12a, which is riveted to the web of the channel member.

1n the modifi tation shown in Fig. 'G the pendent. member is of channel form in cross.`

section at its middle portion with laterally disposed flanges 13, while the web of this member is riveted to the web of the channel member and is of gradually decreasing width from its center toward its end, the fianges and web forming relatively plane surfaces at the end portions so that the ten sion flanges 13 in this modification extend to the web of the. channel'member 1.

.ln Figs. 8 to 10 inclusive is shown a trussed form of carline in which the channel 1 is cambcred as in the other views, while the tension member 15 is formed of a rolled `of adjustment of the tension member in this channel -with its web portion up and with depending flanges 16, While a relatively U- shaped pressing 17 serves as a strut.

In F igs.,11 and 12 is illustrated a modified construction in which the earline comthreaded attheir inner ends and connected by means of a turn-buckler 21,- while the outer ends of these rods 9.0 are flattened at 22 and connected by rivets 23 with the web l of the channel 1, thereby providing means modification.

In 'Figs' 1 to 7 inclusive the cai-line comprisesn a composite member with tension flange, whereas in the modifications shown in the otherv figures a purely tension member is provided.

.'A channel shaped carline without the reinforcement shown and described herein has been used in car construction but has been found to be Weak, in service, and leaky roofs have resulted because of lack of' proper reinforcement of said carlines.

What I claim is:

1'. A carline comprising two members each of which is substantially channel form in cross section, one of said members being a commercially rolled cambered channel and the other being shorter and connected thereto within the chamber of said channel, the

rolled channel being of uniform cross section throughout its length.

2. In a carline, a composite member comprising an outwardly open channel member and longitudinally inclined flanges, and a vertical web extension having a horizontal flange.

3. A carline composed of a cambered compression member With a web and upstanding vertical flanges and a separate tension member secured to `the web'of the compression member near its middle and being flanged horizontally.

a. In a carline, a rolled channel compression member flanged outwardly'and a tension member riveted to the web of said channel at each side of its' middle.

5. In a carline, a eambered channel compression member and a separate shorter tension member, the end portions of which arev secured to the web of said compression member.

G. In a cai-line, a cambered channel member, an inclined flange connected thereto, a

, web pendent from the flange and a flange at the lower edge of the web. v

7. VIn a carline, an outwardly open channel member, a reinforce connected to the web of' the channel member, and tension means pendent from said reinforce.

S. L carline comprising a cambered, outwardly open, channel member, and a channel pressed member having one flange fixed along and within the camber and ha-ving a pendent web and a tension flange at the lower edge of the web.

'9. A carline comprising a commercially rolled channel compression member of constant cross section, and a tension member having its end portions connected to the ,channel by means extending through the web of the channel.

In witness whereof 'I have hereunto set my hand in the presence of two witnesses.
